1 Claim. (Cl. 18324) This invention relates to a humidifier and dust collector for industrial purposes. It has for its main objects to provide such a device that will be highly satisfactory for the purpose intended, simple in structure, comparatively cheap to manufacture, easy to install for use, and extremely durable. A further object is to provide such a device that will be highly satisfactory for cleaning air that is to be used for industrial purposes.

Other objects and advantages will appear from the drawings and description.

By referring generally to the drawings it will be observed that Fig. 1 is a top plan view of a humidifier and dust collector made according to this invention for use in cleaning incoming air by force for any industrial purpose; and Fig. 2 is a sectional view of the parts shown in Fig. 1.

Similar reference numerals refer to similar parts throughout the several views.

Referring to the drawings in detail it will be seen that the device comprises a round container having a top 1, bottom 2, and surrounding wall 3. A plurality of tubes 4 are attached in the top and extend downwardly into the container for a short distance. An air bafile structure consisting of parts 5 being a ring attached around in the upper portion, 6 being a circular plate attached around the bottom edge of the ring, 7 being a slanting portion attached around at the lower edge of the ring, and 8 being a circular plate attached to the lower edge of the slanting portion, all being positioned around tube 9 that is the discharge opening for fresh air drawn in through the device. The top 6 of the air bafile is provided with holes into which the lower ends of the tubes 4 are attached. The part 7 of the air baffle slants toward the main tube 9 so that the entering air will strike the main tube before making contact with the surface of the water 12 in the bottom portion of the container which is provided with water baffles 13 to prevent the water from sloshing around when the humidifier is used.

The structure shown by Figs. 1 and 2 is for industrial use in cleaning air. It is provided with an inlet pipe 17 for water from a source not shown, and a water gage 22. The upper portion comprises a pointed part 24 with a bottom plate 25 that is connected by bars 26 to the outer inverted V-shaped part 27 that fits over the open ends of the tubes 4, it may be attached by any suitable means or remain in place for use by gravity. The ring structure at the top of the double V-shaped portion comprises a flat metal ring integral with the top edge and is for attachment to any incoming air means; the ring structure at the bottom comprises a flat metal ring integral with the bottom edge and is for attachment to any means for making use of the cleaned air. The baffie 6 has its periphery edge bent downward to partly obstruct the passage of air and is positioned to cause the incoming air to travel near the container wall as indicated by the arrows.

The arrows shown in Fig. 2 show how sucked in air travels through the humidifier as follows: the air enters through the tubes in the top of the container, is diverted by the truncated cone portion of the air baffie toward the center main tube which it strikes, then the air flow curves and makes contact with the surface of the water and extends over. the water. to the outer curved edge of the baffle bottom portion, then upward along the inner face of'the Wall of" the container, then along under the container top and between the tubes to the open end of the main center tube, then down through the center tube into the place for use. Thus it will appear that as the air strikes the surface of the water and spreads out to the curved outer edge of the baffle it will absorb moisture from the water and be cleaned of dust and the like fall ing into the water.

The various parts of the device may be made of any material suitable for the purpose, but I prefer to use good grades of metal such as copper and aluminum. Also the parts may be made in different sizes and capacities depending on the amount of fresh clean air is required for industrial use.

While I have shown and described the preferred embodiment of my invention, 1 do not wish to limit same to the exact and precise details of structure, and reserve the right to make all modifications and changes so long as they remain within the scope of the invention and the following claim.

Having described my invention I claim:

A dust collector comprising a round container, said container having a top and bottom and surrounding wall and being shaped round, said top having a plurality of round similar in size holes therethrough and spaced evenly apart to form a circle, a piece of round tube attached by an end thereof in each of said holes and extending into the container a short distance, a bafile structure in the upper half of the container adapted for directing air passing through the container when in use, said baffle structure having a top round portion and a bottom round portion and a truncated cone shaped portion connecting the top and bottom portions together with space between them, the said bottom portion having a comparatively large hole through its center, the inner edge of the truncated cone. portion being attached to the edge of the said large hole in the bottom bafile, said top baffle portion having a plurality of holes therethrough of a size and positioned to register with the holes in the container top, each lower end of said pieces of tube being attached in a hole in the top of the baffle structure, the said top and bottom of the bafile structure having their peripheral edges positioned near the wall of the container, the top of the bafiie structure having a comparatively large hole through its center, the bottom of the container having a round hole through its center portion the same size as the center hole in the top of the baffie structure, a tube of a size to fit into the said center hole in the top of the baffle structure and the hole in the bottom of the container, the top edge of the tube being attached to the edge of the center hole in the top of baffle, the lower end portion of the tube extending through the hole in the bottom of the container and being attached to the edge of the hole at a point above its portion extending out of the container, a ring portion, said ring portion being attached to the end of the extended portion of the said tube and being adapted as connecting means for use of the entire structure, a double round V-shaped structure with space between them, bars attached in the V-shaped structure, said bars being attached to the inner face of the outer V-shape and the outer face of the inner V-shape as means for holding them spaced apart, said outer portion of the double V- shaped portion being of a size to rest upon the top of the container and register with the said holes having pieces of tube attached therein to thus form a passage way for air to be drawn into the tubes in the container and downward through the tubes, then through the truncated cone shaped portion, then outward under the lower face of the bottom bafiie, then upward near the wall of the container, then inward and over the curved edge of the top of the baffle and between the said pieces of tube, then downward through the large tube in the center, then outward for use as clean air, a secondring structure, said second ring structure being attached around the outer edge of the said double inverted V-portion as attaching means for the entire structure.
